Live Portrait vs. Hedra: AI Facial Animation Showdown & Tutorial

The paragraph introduces the topic of facial animation using AI, specifically focusing on the Live Portrait technology. It discusses the evolution of facial animation since the presenter's earlier videos on avatarify theater and other apps like Mug Life and Expression. The presenter notes that Live Portrait differs from real-time apps like Hedra, as it requires a pre-recorded video to drive the facial animation. The comparison between Hedra and Live Portrait is highlighted, with Hedra being audio-driven and Live Portrait being video-driven. The paragraph also mentions the process of creating an animation with music, starting with composing tracks in Adobe Audition and converting voices using Otomy.

This paragraph delves into the process of voice conversion and image generation for the animation project. The presenter exports vocal tracks and uses Otomy to shift the pitch to create different voices. The goal is to find the best voice for the animation. The paragraph also discusses the use of Prome AI to generate images of a 1940s-style jazz female singer, with a focus on getting a direct camera-facing image for better animation results. The presenter experiments with image variations and lighting to achieve the desired look for the animation.

The paragraph explains the process of setting up animations in Hedra and Live Portrait. The presenter uploads the generated images and audio tracks into Hedra to create animations. It mentions the importance of testing the audio tracks together before committing to the animation process. The paragraph also covers the technical aspects of installing Live Portrait and using it with Compy UI, suggesting viewers refer to another video for detailed installation instructions. The presenter shares a workflow for Live Portrait, including adjustments to the eye and lip retargeting multipliers for more natural animations.

This paragraph focuses on recording and adjusting the driving videos used to animate the facial expressions in Live Portrait. The presenter discusses the challenges of being too close to the camera and the resulting distortions, as well as issues with excessive head movement and hair that's too prominent. The solution involves re-recording the driving videos from a greater distance to reduce distortion and choosing images with less prominent hair. The paragraph also covers the process of cropping videos into a square format and adjusting frame rates for compatibility with Live Portrait.

The paragraph describes the final steps in creating Live Portrait animations, including fine-tuning the parameters for eye and lip movement to achieve a more natural look. The presenter tests different multiplier values to reduce the exaggeration in the animations. The paragraph also covers the process of creating images with shorter hair to avoid issues with hair tearing in the animation. The presenter experiments with different images and driving videos, adjusting parameters to improve the quality of the animations. The paragraph concludes with a demonstration of the final animations, showcasing the improved results after making the necessary adjustments.

In the final paragraph, the presenter wraps up the video by emphasizing the versatility of Live Portrait for various types of facial animations, not just for singing but also for speaking and any face-like imagery. The paragraph serves as a call to action for viewers to subscribe to the channel for more cutting-edge content on AI and technology.
